Reading and displaying tabs in PHP

I read and display a file this way:

<some code here>
while(!feof($file)) {
$number++;
$result .= "<tr><td width=\"11\">$number.</td><td>". fgets($file) ."</td></tr>";
}
<some code here to finish the html table>
echo $result;

The problem is that when the table is displayed, tabs are not displayed. Thereby, the structure of the text, if tabs are used, is not correct.

By tab you mean the whitespace \t ? Your function fgets($file) gets only the string values so reading the file:
"This is     just a text."
will get [this] [is] [just] [a] [text] (without a tab after "is").

Hope this helps
$result ='<table "width=100%">';
while(!feof($file)) {
$number++;
$result .= "<tr><td width=\"11\">$number.</td><td>". fgets($file) ."</td></tr>";
}
$result ="</table>";

echo $result;

Raods Roads: I need to display also the tabs. How would I do that?
shinug: you replaced my pseudocode(if you can call it that), with real code. That was not my intention :)

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Can you post a sample of that text file ?

Shinesh PremrajanTechnical ManagerCommented:
Try either of these, as the text file need to be binary safe, b and t tags cane be used for such cases.

$handle = @fopen("test.txt", "rb");

$handle = fopen("test.txt", "rt");

Hope this helps

The tab can be seen in the View source of the page, it wont be visible in the browser.For the browser to display the tabs you need to wrap the txt in <pre> tags.

Hope this helps

Tabs are whitespace and browsers collapse multiple whitespace down to a single space. This leaves you 3 options

1. Use <pre></pre> tags as outlined by shinuq above
2. Replace each tab with non-breaking spaces using str_replace   .... str_replace("\t",  "&nbsp;&nbsp;&nbsp;", $text);
3. Use table cells or CSS styling to simulate the tabs.

No.s 1 or 2 are probably the simplest to use especially if you use a monospaced font

FYI,  

str_replace("\t",  "&nbsp;&nbsp;&nbsp;", $text);

wont pickup the \t in your text it .. :-)

The line I ended using was:
$result .= "<tr><td width=\"11\">$number.</td><td>". str_replace("\t",  "&nbsp;&nbsp;&nbsp;", fgets($file)) ."</td></tr>";

It worked with me.
Why did you suspect that it wouldn't work? Just curious..
